Abstract

A remote control system for operating a controllable unit includes a remote control device and a remotely-controlled device. A method for operating the remote control system includes the steps of transmitting a signal from the remote control device to the remotely-controlled device, transmitting a command signal from the remote control device to the remotely-controlled device, selectively transmitting an authorization request signal from the remotely-controlled device, transmitting a response signal from the remote control device to the remotely-controlled device, and verifying the response signal of the remote control device by the remotely-controlled device such that a controllable unit can be driven by the remotely-controlled device.

Claims

1. Remote control device for operation of at least one controllable unit such as a drive unit attached to a moveable part such as a door, a gate, a window, blinds, shutters, or a curtain, an awning or the like, where the remote control device comprises a remote control unit and a remote-controlled unit designed in such a manner that the remote control unit may transmit coded control signals and in that the remote-controlled unit may receive and react upon said coded control signals, characterized by

both the remote control unit (10) and the remote-controlled unit (20) comprising one and the same code,

by the remote-controlled unit (20) comprising means for generation and transmission of an authorization request signal (60) upon receipt of a command signal (50) from the remote control unit (10),

by the remote control unit (10) comprising means for generation and transmission of a response signal (70) to the authorization request, and

by the remote-controlled unit comprising means for verification of such a response.

2. Remote control device according to claim 1 characterized by the means of the remote-controlled unit for generation and transmission of an authorization request signal (60) comprising means (24) for generation of random signals.

3. Remote control device according to claim 1 or 2 characterized by the means of the remote control unit for generation and transmission of a response signal (70) to the authorization request signal (60) comprising means for carrying out a coding of at least part of the information of the authorization request signal by means of its code and by the means of the remote-controlled unit for verification of the response signal comprising means for carrying out a coding of at least part of the information of the authorization request signal by means of its own code and means for carrying out a comparative procedure by means of these two coded signals.

4. Remote control device according to claim 1, 2 or 3 characterized by the remote-controlled unit comprising encryption means for encryption of said authorization request signal (60) by means of said code in the remote-controlled unit and by the remote control unit (10) comprising encryption means for encryption of the response signal (70) by means of said code in the remote-controlled unit.

5. Remote control device according to one or more of claims 1-4 characterized by the remote-controlled unit (20) comprising means for detection of received non-critical command signals and by the remote-controlled unit being designed to comply directly with such non-critical command signals.

6. Remote control device according to one or more of claims 1-5 characterized by the remote control unit comprising one or more remote-controlled units (20), and by each of the remote-controlled units comprising a unique address.

7. Remote control device according to one or more of claims 1-6 characterized by the remote control device comprising two or more remote control units (10) and by said two or more remote control units comprising one and the same code.

8. Remote control device according to one or more of claims 1-7 characterized by the remote control device comprising two or more remote-controlled units (20) and at least one remote control unit (10) wherein the address of each of the remote-controlled units has been stored and wherein said addresses are divided into one or more groups.

9. Method of configuration of a remote control device designed for operation of at least one remote-controlled unit such as a drive unit attached to a moveable part such as a door, a gate, a window, blinds, shudders, or a curtain, an awning or the like, where the remote control device comprises a remote control unit and a remote-controlled unit designed in such a manner that the remote control unit may transmit coded control signals and in that the remote-controlled unit may receive and react upon said coded control signals, characterized by

the provision of one or more remote-controlled unit provided with an address each,

the provision of a remote control unit provided with a code, and

an initiation command from the remote control unit resulting in one or more of said remote-controlled units transmitting the(ir) respective address(es), which are being received and stored by the remote control unit and by said code being transmitted to and stored by the remote-controlled unit(s) in question.

10. Method according to claim 9 characterized by said code being stored by one or more of said remote-controlled units that have not previously been provided with a code.

11. Method according to claim 9 or 10 characterized by said code being stored in the respective remote-controlled units in such a manner that it cannot be overwritten by a new configuration.

12. Method according to one or more of claims 9-11 characterized by a further group configuration of the remote control device being carried out whereby the remote control unit is brought to a programming state and whereby one or more of the addresses stored in the remote control unit are attached to one of one or more user-specified groups.

13. Method according to one or more of claims 9-12 characterized by a code already stored by a remote-controlled unit being removed by carrying out a reset procedure on said remote-controlled unit prior to initiation of a configuration of the remote control device wherein said remote-controlled unit forms part or is to form part.
